New Zealand kiwi are flightless nocturnal birds driven to near-extinction by introduced predators, with ongoing conservation efforts.
Wild kiwi suffer enormously from predator attacks, with stoats causing deaths that are often slow and painful. Kiwi caught in traps set for introduced predators also experience welfare harms. Conservation interventions like chick captive rearing can cause stress but save lives. The overall welfare calculus favors intervention, though methods matter.
